number of fingers used is, of course, not limitcd to the number shown and described for illustrative purposes,

With this invention constant vscuum is maintained in any well known Way upon the vacuum port (I and compressed air in any well known way is meintoined coniinually within the air, inlet port i The hollow conical plug 12 is also caused to oscillsie in any well known way with the result thet when the main chamber vacuum port 22 is in alinement with the vacuum port t; a vacuum is formed in the chamber 15. Act the same time the chamber vacuum ports 23, ill and 25 are in elinement with the air and vacuum poi-is 8, 9 and. 10 which communicats with the nipples, 52, 5* and 56. Vacuum thus obtains m the palm e8, first finger 51, second finger 53, and third. linger simultaneously and there is no pressure upon the test. As the plug 12 continues to oscilaforementioned are disalined and closed to each other. The first chamber air inlet port 16 comes into communication with the air inlet port- 4:, compressed obtaining? within the chamber 15, At the same time the chamber air outlet port 19 is in communicefiion with the first air and vacuum port 8. Compressed air then obtains within the palm 4-8 and first fingeriil, inflating the some and compressing the test near its root. The plug continuing to move, the second chamber air inlet port 17 in turn alines itself with the air inlet port 4-. At the some vacuum port}. Compressed air then obtuinsin and inflates the second independent finger 53. By the elongation of the first palm 48 and first linger 51 still continue to receive compressed air. The plug continuing to move the third chamber air inlet port 18 in turn comes into'slinement with the air inlet port 4. At the same time the lhird chamber airioutlct port 21 is in communi cation with the third/air and vacuum port 10. Compressed air is then communicated to the third finger inflating By the elongation of the second chamber ai'r outlet port 29, however, the second finger 53 still continues to receive compressed )1 All flexible bags are now inflated, the'teet being compressed between the fingers and the palm The movement oi the plug conmuing, it is now returning, all the ports eventually become disalincd with the exception of me shell atmospheric port 57 andthe main chamber atmospheric air port 58, which, if used alone, permit the compressed air then looked within the chambe 15 to escape into the sin. snhere, Shoul the atmospheric airports 59, 60 and 61 be i also used these come into elm-ement with l the air and vacuum ports 8, 9 and 10 when the ports 57 and 58 are in alinement. The compressed sir then confined within the palm es and fingers 51, 53 audoo then escapes into the atmosphere. The plug" continuing to move the atmospheric air ports are disali'ied and the vacuum ports once more slined with the resultalready described.

Having now described my invention, what I claim new and desire to secure by Letters Potent is l. Milking apparatus having a pulsutor comprising a shell. a compressed air inlet port in said shell. a vacuum inlet port in said. shell, a plurality of combined air and vacuum ports in said shell adapted to lend to a test cup divided into aplurality of c0mpurtments, a hollow valve plug within said shell. ports in said plug adapted to place said combined air and vacuum ports successively in communication with the compressed air inlet port, and ports in said plug adapted to place said combined air and vacuum ports simulisneously in communicm tion with the vacuum inlet port.
